NANOG Meeting Presentation Abstract

Rapid Convergence in IP Networks
Meeting: NANOG46
Date / Time: 2009-06-15 12:30pm - 1:00pm
Room: Regency Ballroom, 2nd FL Mezz
Presenters: Speakers:

Tom Scholl, AT&T Labs

Within the Global IP/MPLS backbone design & development team, his role is to design routing architectures for the core network and work on network integration of the legacy SBC Internet Services network to the AT&T common backbone. Tom has spent his last several years at SBC and Ameritech working in both operations and network engineering roles. He has presented several times at NANOG and always makes time available to help peers and distribute clue where needed.
Abstract: This presentation covers the topic of rapid convergence within IP networks. IP networks are frequently stated to not be capable of providing rapid convergence similar to that of SONET transport networks. However, with the right knob turns and a properly designed network, you can reach that 50ms or at least sub-second convergence target. The presentation will outline what applications require such performance, what protocols can deliver the results and how well it actually works in production. Additional lessons learned will be outlined showing operators that its not as simple as flipping on a switch. A list of commands and knobs are given at the end of the presentation to get operators a starting point to improve performance within their own networks.
